You can attach any standard small battery cell charger (but _not_ an automobile type) from 5V-16V and 150 milliamps-1 amp. I give these specifications because I have used them. If you use a weaker battery charger, expect the charge time to be approximately a day. If you use a stronger charger, be careful! Check for overheating and be aware of a possible explosion or rupture of the battery (which is actually always possible, just not likely under standard charge conditions). Before you try to charge the battery, check the charge on the (+) and (-) contacts, they are marked on the battery, using a standard voltmeter or multimeter (checks volts, amps, ohms, etc.). If the charge is over 4.5V, then you likely have a dead microprocessor and will have to replace that also. If the charge is less then about 4.5V, then you can try charging from you battery charger. I have connected my battery to my charger using two sewing needles bent at about 10 degrees, about 7 mm from the sharp end of the needle. I insert the needle into the battery between the contacts [either (+) or (-)] and the surrounding plastic. Take care to notice which part of the plastic is stronger because it will bend and crack off if you are too rough with it. Insert one needle between the (+) contact and the surrounding plastic and the second needle between the (-) contact and the surrounding plastic. Use two wires with alligator clips at both ends to connect the needles to the appropriate contacts on the battery charger, [(+) on battery to (+) on battery charger, etc.] Check for the battery becoming too hot. Check the charge about once an hour. If the charge will get to about 5V then the charging circuitry of the PowerBook will recognize the battery, as long as the microprocessor is working. If the battery charge will not rise to 5V, it has dead cells and needs to be rebuilt, given to someone who will rebuild it, or recycled.

Then insert your battery. If IBR doesn't like your battery, shut it down, take your battery out and restart IBR. Do this up to 10 times and allow the program to charge your battery each time. You should be able to get enough charge during this process to allow the battery memory to be read. Then let the program continue processing your battery. You can also use a stock battery charger of about 9V and 150 millamps or more up to 1 amp to manually charge the battery (You will need to devise an attachment method, but I can help you on that). Once you have the battery charged, you need to drain the battery using Battery Amnesia and fully charge it back up about 5 times or until you see no further improvement in battery life. -- PowerBooks is sponsored by http://lowendmac.com/ and...

Re: PB 5xx Battery repair
If I wanted to order this part from Digikey, would I just look for eeproms and type 93c66? An elusive part, Digikey carries only a few of the many possible configurations. Specifically, the AT93C66-10SI-2.7-ND, at $1.20 each, or $1.10 each for 25-99 devices. -- PowerBooks is sponsored by http://lowendmac.com/ and...

Of the two batteries which came with the machine, one was properly programmed already and it charged fully; the other still needs to be reprogrammed before I attempt to charge it. How is this reprogramming of a 540c battery accomplished?? When I try EMM (the recommended battery refresh program) I always get the text that it is immpossible to remedy anything about the battery. There is a utility from VST that tests and re-programs the battery (cannot think of the name at the moment, even though I was using it last night), also there is the Apple 'smart battery update' there is also a utility by Lind that does much the same, however I have just been re-building some 5xx batteries and out of 5 I was playing with 3 had faulty eeprom chips (they had a stuck bit and would not re-program even in a stand-alone programmer after removing,) I ended up copying the data from a good chip to brand new chips and then running the batteries through the VST and Lind utilities, I am now in the middle of checking them, so far it is looking good. If you need the utilities then I could e-mail them to you tomorrow or Monday. Ben.

Total time (inc removing the board from the battery) about 30 min each I then used the apple battery updater (the original was not updated) and verified it with EMMpathy. This has also cured the 'sleep drain bug' that they were all previously showing. It may be possible to fit a blank eeprom and use the Lind intelligent battery utility to program it as it will reset the memory to the factory default if it is badly corrupted, however I have not tried it with a blank chip. all 3 old chips had a stuck bit in the same location ! this was confirmed with the eprom programmer, although 1 of the old chips re-programmed ok about 1 time in 10.
